Winter Field Lab: Snow Hydrology
This is a great field activity to implement during late winter or early spring when things have not quite thawed. It integrates basic science with original geohydrological research. Students get to go out into the field and collect their own data from a snowpack. They measure water equivlalent, identify types of snow metamorphism, find evidence of the winter's precipitation patterns, and judge possible snowpack hazards. Back in the lab, students evaluate their data, draw conclusions, and make a report.
- Learn snowpack studying techniques, determine amount of water residing in a snowpack, and compare results to previous data, if any.
Context for Use
This activity is designed for upper-level undergraduate and graduate-level geohydrology courses.
Teaching Notes and Tips
Emphasizing that the students are doing original research and that there are no pre-determined answers to posed questions enhances their interest in the project.
- Snow shovels
- Snow tubes
- Hanging scales
- Snow kits (including: thermometer, soil knife, and snow-density measurement device)
- Topographic maps of area
- Handheld global positioning system (GPS)
- USDA avalanche handbook
Report due two weeks after field day. Evaluate reports based on the quality of the science, writing, and calculations. In addition to the teacher evaluation, letting class members evaluate and edit another student's report gives students a chance to practice critical evaluation of another's work, which is found to enhance the re-writing process.
